在线考试系统实现：PureScript与倒计时 + 自动判卷

随着互联网技术的飞速发展，教育行业也在不断变革。在线教育作为一种新型的教育模式，越来越受到人们的青睐。其中，在线考试系统作为在线教育的重要组成部分，能够有效提高考试效率和准确性。本文将围绕PureScript语言，探讨如何实现一个具有倒计时功能和自动判卷功能的在线考试系统。

PureScript简介

PureScript是一种函数式编程语言，它基于Haskell，旨在提供一种简洁、高效、易于理解的编程方式。PureScript具有以下特点：

- 函数式编程：强调函数和纯函数的使用，避免副作用。
- 类型安全：通过静态类型检查，减少运行时错误。
- 模块化：支持模块化编程，提高代码可维护性。
- 兼容JavaScript：可以无缝地与JavaScript代码交互。

在线考试系统设计

系统架构

在线考试系统可以分为以下几个模块：

1. 用户模块：负责用户注册、登录、个人信息管理等。
2. 考试模块：负责考试题库管理、考试创建、考试开始、考试结束等。
3. 题库模块：负责题库的创建、修改、删除等。
4. 判卷模块：负责自动判卷、成绩统计等。

技术选型

- 前端：PureScript + React
- 后端：Node.js + Express
- 数据库：MongoDB
- 倒计时：JavaScript定时器
- 自动判卷：算法实现

实现步骤

1. 用户模块

我们需要创建一个用户模块，用于处理用户注册、登录等操作。以下是使用PureScript编写的用户注册功能的示例代码：

```purescript
module User where
